FRANK OPELT, or MUSCATINE, IowA.

SCAFFOLDING-SUPPORT.

Specification of Letters Patent.

Application filed December 6, 1913.

Patented Aug. 11, 1914. Serial No. 805,056.

To all whom it may concern:

Be it known that I, FRANK OPELT, a citlzen of the United States,residing at Muscatine, in the county of Muscatine and State of Iowa,have invented certain new and useful Improvements inScaifoldingSupports, of which the following is a specification.

In building scaffolds of various heights, it is necessary to constructhorses on each height. Said horses are unwieldy and cumbersome anddifficult to transport from place to place, which frequently results ina waste of material, inasmuch as the lumber from which the horses areconstructed is frequently broken in taking the horses apart and damagedto such an extent as to make it practically useless.

The object of my invention is to provide a support for a scaflolding towhich uprights of varied lengths may be detachably secured, according tothe height desired, and from which the uprights may bereadily detachedwithout injury.

The support may be adjusted to various heights on the timbers, so thatone set of timbers may be used for supporting scaffolds at variousheights within the length of the timbers.

With these and minor objects in view, my invention consists in the partsand combination of parts as will be hereinafter more fully set forth.

In the drawingFigure 1 is a perspective View of a scaffold embodying myinvention; Fig. 2 is an enlarged detail end view of the same with partof the scaffolding omitted; Fig. 3 is an enlarged detail View of thescaffold support.

The reference numeral 1 indicates the vertical timber supports or legsof the horse, 2 the transverse scaffolding support, and 3 the scaffoldboards.

The scaffold support embodying my invention consists of two uprights 4which converge upwardly toward each other.

5 is a transverse support secured between the upper ends of the uprights4 and depending below said ends. This transverse support may be of anydesired size.

6 are collars extending laterally and outwardly from the uprights 4: andof a diameter to be selected according to the size of the legs of thehorse to be used. In this connection, I would say that I find that theuniversal size of timbers sufficient for the average scaffolding usedaround a building is 2 by l. Each collar 6 is provided with openings intheir side walls in which a clamping screw 7 is adapted to project toclamp the legs therein. At the top of each upright f, I locate a clampscrew 8.

9 are lugs projecting outwardly from the uprights at near their lowerends, which, co-acting with the collars and screw clamps, serve to holdthe legs of the horse in upright alinement with the uprights I as willbe readily understood.

9 are set screws mounted in said lugs.

After having selected the length of timber required for the scaffolding,said timber is passed through the collars 6, and after the support hasbeen adjusted on said timbers to the required height for thescaffolding, the pins 7 are passed through the openings in the collarsand through a corresponding opening in the timbers. The lugs 9 receivethe legs between them and the set screws are adjusted against thetimbers thus keeping the timbers in alinement with the uprights. Thetimbers are further secured to the support by means of the screw clamps8. The

supports being thus rigidly secured to the timbers, the transversescaffolding support 2 is supported in the transverse support 5 tosupport the scaffolding boards 3.

10 is a brace extending from the lower end of one of the uprights 4 tothe lower end of the other upright 4 which serves as a combined tensionand compression member for the scaffolding support which prevents theuprights spreading apart or collapsing.

I claim An integral scaffolding support comprising uprights, a combinedtension and compression member connecting said uprights at their lowerends and extending therebetween, a substantially U-shaped timber supportconnecting the upper ends of said uprights and depending therebetween,clamp screws carried by said timber support out Wardly, timber collarsextending from said The foregoing specification signed at Musuprightsintermediate their ends, clamp catine, Iowa, this 15th day of November,screws carried by said collars, and an out- 1913. wardly extending pairof lugs at the bottom FRANK OPELT. 5 of each upright in alinement withthe said In presence of two witnessescollars, and clamp screws carriedby said M.
